Into the furnace we went!
The start of July was relatively cool and mainly cloudy, with short periods of rainfall being typical in the first week, although quantities were small.
The 6th was a windy day for July. Temperatures then began to rise after the first week, with some forecasts indicating a spell of very hot weather around 17th.
The weather was in spectacular form for the Durham Miner’s Gala on 9th July, with blue skies and warm, dry conditions. There wasn’t a cloud in the sky. Great for guzzling beer!
By 11th July, the mean stood at 18.0 degC (Mean Max 22.3, Mean Min 13.6), with only 5.9 mm of rain collected.
As we got closer to the forecast hot spell, it was expected that the extreme predictions would moderate a bit. Models were showing that the 40 degC mark could be breached over the period 17th-19th July. This wasn’t the case, the predictions firmed up and it was clear that we were in for some seriously hot weather!
Sunday 17th July
The warnings started coming in, and they were upgrades!
At first, it seemed that the hottest temperatures were going to be Sunday/Monday, but they were pushed back a couple of days. The top temp in Gilesgate on Sunday 17th was a modestly warm 27.8 degC.
Monday 18th July
The temperature hit 33.7 degC, which equalled my record from July 2019. It was getting seriously hot, but was forecast to get hotter still. Reports started to come in of wildfires destroying property and farmland in the tinder dry conditions across the country.
Tuesday 19th July
The excitement was building by the hour. By about 10am on the morning of 19th, the old national record from Cambridge Botanic Gardens (38.7 degC) had been easily eclipsed. Other stations started to report hotter and hotter temperatures.
Would the 40 degC mark be beaten? It was beaten in a couple of places, but the new record is now from Conningsby, Lincolnshire, at 40.3 degC. The east side of the country was the hottest, and the high temps pushed a long way north, including high into Durham.
As seen in the video, my site in Gilesgate reached 37.5 degC. At Durham University Observatory on Potters Bank, the new record was 36.9 degC. This obliterated the old record by 4 degrees. A historic day.
For the month as a whole, the mean was 18.2 degC. This ranks in the top three warmest ever Julys. The average daily high was 23.0 degC, and 10 days hit 25.0 degC or higher.
Rainfall
As is usual after a hot spell, the atmosphere provided a lot of moisture, and 50+ mm fell in the last 10 days to give a total of 65.3mm, which is normal for July. The wettest day was the 25th, with 24.4mm counted.
